A specially crafted username can bypass SIEM ESM authentication (password is not validated) if the ESM is configured to use Active Directory or LDAP authentication sources. This can result in the attacker gaining NGCP (master user) access to the ESM.

This update resolves an issue where the login username is mishandled.

CVE-2015-8024

McAfee Enterprise Security Manager (ESM), Enterprise Security Manager/Log Manager (ESMLM), and Enterprise Security Manager/Receiver (ESMREC) 9.3.x before 9.3.2MR19, 9.4.x before 9.4.2MR9, and 9.5.x before 9.5.0MR8, when configured to use Active Directory or LDAP authentication sources, allow remote attackers to bypass authentication by logging in with the username “NGCP|NGCP|NGCP;” and any password.
